Software Release 2.7.1
C613-02021-00 REV F

FLASH memory is like a flat file system, with no subdirectories.

File names of up to 16 characters long, with extensions of 3 characters (DOS
16.3 format), are supported on the router. However, files on the router are
stored

in FLASH using the DOS 8.3 format of 8 characters long, with

extensions of 3 characters. For example, the file

extralongfilenam.cfg

may

be saved as

extral~1.cfg

in the FLASH File System. Therefore, files can be

accessed via two file names, either of which can be used for file management.

A translation table, named

longname.lfn

, converts file names between DOS

16.3 format and DOS 8.3 format. To reconcile file names the router consults the
translation table which is synchronised with file contents in memory. For more
information about working with files see the Working With Files section in the
Operation chapter in the Software Reference.

To display the files in FLASH, enter the command:

SHOW FILE

Figure 9: Example output from the SHOW FILE command.

The Locks field indicates the number of concurrent software processes using the file.

The router automatically compacts FLASH memory when a maximum
threshold of deleted files is reached. Compaction frees space for new files by
discarding garbage. A message will appear when FLASH compaction is
activated. Another message appears when FLASH compaction is complete.

While FLASH is compacting, do not restart the router or use any commands
that affect the FLASH file subsystem. Do not restart the router, or create, edit,
load, rename or delete any files until a message confirms that FLASH file
compaction is completed. Interrupting flash compaction may result in damage
to files.

Using Scripts

When you start or restart the router, or when it automatically restarts, it
executes the configuration commands in the boot script. A boot script is a text
file containing a sequence of standard commands that the router executes at
startup. The default boot script is called

boot.cfg

. Commands run from a boot

script are limited to 128 characters.
